Gloster Gladiator hashing the sky

A little posterization hashing experiment. I specifically picked this file (by NamelessFaithlessGod , I could not trace the specific link of the file) because the plane and the upper right portion of the picture are mostly gray tones, while the bottom left lends itself for mild posterization tones. It turned out quite as expected, soft sky emphasis, not grotesquely disturbing, adding a feel of movement to the still.
